CVE-2026-31196: n/a
The traceroute diagnostic handler in /bin/httpd_clientside for ALTICE LABS / SFR France GR140DG and GR140IG fibre CPE/Router/Gateway, inserts unsanitized user input into a system() call, allowing authenticated remote attackers to execute arbitrary commands as root via crafted destAddr parameters using shell command substitution.
AI Analysis
Technical Summary
The traceroute diagnostic handler in /bin/httpd_clientside on ALTICE LABS / SFR France GR140DG and GR140IG fibre CPE/Router/Gateway devices improperly sanitizes user input in the destAddr parameter. This input is passed directly to a system() call, enabling authenticated remote attackers to execute arbitrary commands with root privileges via shell command substitution. The vulnerability is documented as CVE-2026-31196 and was published on 2026-05-05. No CVSS score or remediation details are currently available.
Potential Impact
Successful exploitation allows authenticated remote attackers to execute arbitrary commands as root on affected devices. This can lead to full compromise of the device, including unauthorized control over network traffic and device configuration. The impact is significant given root-level command execution, but exploitation requires authentication.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected diagnostic functionality to trusted users only and monitor for unauthorized access attempts. Avoid exposing the affected devices' management interfaces to untrusted networks.
